TICKET-PUNCH.

SPECIFICATION forming part of Letters Patent No. 285,867, dated Octoberk2, 1883.

Application filed August 15, 1883.

To all whom, it may concern.-

Beit known that I, ROBERT VooDMAN, of Malden, in the county of Middlesexand State of Massachusetts, have invented an Improvement inTicket-Punches, of which the following is a full, clear, and exactdescription, reference being had to the accompanying drawings, makingpart of this specification, in whichy Figure 1 is a side elevation of aticketpunch constructed in accordance with my invention. Fig. 2 is alongitudinal vertical seetion through the center of the same with theparts in a different position. Fig. 3 is a plan ofthe under side of thesame. Fig. 4 is a section on the line xx of Fig. 1. Fig. 5 is a seetionon the line y y of Fig. 1.

My invention relates to certain improvements on the punch for whichLetters Patent ofthe United States were granted to Cyrus B. Holden,August 14, 1866, No. 57 ,136, and has for its object to facilitate theegress or discharge of the chippings or pieces cut from the articlebeing punched, whereby they are prevented from accumulating within thepunch and obstructing the moving parts thereof', as frequently occurs inpunches made in accordance with the aforesaid patent of C. B. Holden,and which has proved to be a serious objection to their use.

To this end my invention consists in providing one of the leversimmediately above the ticket-slet with an open space extending along theentire length of the ticket-slot and up therefrom into the groove withinwhich is placed the arm which carries the male die,

4and also in providing an aperture extending from the lower side of theticket-slot down through the head of the lever .in line with the iirstaperture above referred to, by which construction a free outlet isafforded for any chippings which may chance to be carried up with themale die, and which have heretofore often introduced themselves betweenthe arm which carries the male die and the sides and bottom of thegroove -or recess in which it worked, thus interfering with its freemovement, the bottom of the said groove having been heretofore closed toform one of the walls of the ticket-slot, and having been provided witha (No model.)

single small aperture only at its front end for the passage of the maledie.

My invention also consists in providing the f 'having at one end a heador enlargement, '1), in the upper portion Aof which is formed a deeplongitudinal groove or recess, c, within which, at its forward end, ispivoted at d, the' lever B, which bears at c upon the upper side of anarm, C, also situated within the groove c, and pivoted near its rear endon a transverse pin, f, the said arm C being kept in contact with thelever B by means of a Afiat spring, g, secured at one end to the lever Aand bearing at its opposite end upon the rear end of the arm C. 'Thehead b of the lever A is divided into two parts, l() 12, by a deeptransverse slot, h, which is intended for the reception of the ticket orother article to be punched, the said slot extending longitudinallyinward from the outer end of the punch. The forward end of the arm C hassecured to it the male die or punch i, which, when the arm O isdepressed by means of the lever B, passes down across the sloth into thefemale die k in the portion 10 of the head b, to perforate the ticket orother article previously entered within the sloth.

The construction thus far described is substantially the same as that ofthe punch described and shown in the aforesaid patent of C. B. Holden,and forms no part of my present invention, being merely referred to inorder to clearly illustrate my improvements thereon, which will new bedescribed.

The bottom of the groove c (which in `the Holden punch was merelyprovided with a small aperture near its front end for the passage of thepunch) is entirely cut away from the front end of the portion 12 of thehead b backward, leaving immediately beneath the arm C an open space, m,extending from the ICQ groove c down into the slot h, a free outletbeing thus Vafforded for the escape of any chippings or pieces punchedfrom a ticket or other article, which may be carried up by the male diezinto the groove or recess c, and which have heretofore been liable toaccumulate between the arm C and the closedv bottom and sides of thegroove c, andl thus obstruct the said arm and render the punchinoperative. The lower portion, l0, of the head b is also provided witha long narrow aperture, a, extending downward from the slot 71y throughto the outside, as seen in Figs. 2 and 5, and situated in line with thespace m, in order to af ford a means o'f escape for any chippings whichmay pass down from the groove c into the slot h, or be carried into thelatter by the Ypunch'i in its ascent, all liability ofthe punch becomingobstructed by chippings or dirt being thus avoided, and the cost ofrepairs materially reduced'.

In each side of the portion l2 of the head b is formed a long na-rrowslot, 1),'eXtending into the groove or recess c, whereby a eonvenientmeans is afforded for cleaning out any chippings or dirt Vwhich maycollect between the upper surface of the arm C and the under side of thelever B, thus avoiding the inconvenience and delay caused by taking thele- `vers A and B apart, as has heretofore been 3o and provided with anopen space, m, immediately beneath the arm C, extending from the groovecinto the ticketslot lz, and with a discharge-aperture, n, in theportion 10, extend ing' downward from the slot h, all constructed andarranged to operate substantially in the manner and for the purpose setforth.

2. In a ticket-punch, the combination, with the lever B and thedie-carrying arm C, of 4 5 the lever A, having apertures p in its sides,extending into vthe groove c, in which the arm C is pivoted,substantially as and for the purpose described.

Witness my hand this 11th day of August, 5o A. D. 1883.
